PUMP.

SPECIFICATION forming part of Letters Patent No. 597,868, dated January 11, 1898. Application filed November 21, 1896. fierial No. 612,944. (No model.)

To call whom it may concern.-

Be it known that I, CHARLES C. WORTH INGTON, a citizen of the United States, residing at Irvington, county of VVestchester, and State of New York, have invented certain new and useful Improvements in Pumps, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

In many processes of manufacture-such as sugar-making, tanning, distilling, brewing, &c.-it is impracticable to use the common composition suction and force valve seats set into cast-iron on account of the corrosive action of the liquid, which attacks the joints between the seats and iron and rapidly destroys them, so as to cause a leak from one side of the valve-plate to the other. i

It is important, therefore, that the valveplates, including the valve-seats, be made entirely of a material or composition not in: juriously acted upon, and this result is socured economically by interposing separate valve-plates of suitable material between the iron castings forming the water-cylinder and the suction and force chambers.

The object of the present invention is to provide a construction of this class employin g such separate valve-plates which shall be simple, cheap, and efficient and especially to provide a construction which shall avoid irregular forms and consequent expense, secure short and direct passages between the suction and force chambers, so as to avoid extended or tortuous passages and internal joints subjected to the action of the fluid, and reduce as far as practicable the floor-space occupied by the machine. This result is secured by arranging the valve-plates edgewise in relation to the water-cylinder, instead of fiatwise, as usual and the present invention includes, broadly, a pump having a valve plate arranged edgewise to the water cylinder or cylinders with the suction and force chambers at the side of the plate. Many arrangements of the cylinders and pulsation, suction, and force chambers may be made embodying this invention; but in the preferred construction for a double-acting pump the suction and force chambers are arranged between the valveplates for the opposite ends of the cylinder,

and such a construction forms a part of the present invention.

The invention includes also various specific features of construction, some of which relate to duplex pumps, and the invention therefore will be illustrated in connection with such a pump.

For a full understanding of the invention a detailed description of a construction embodying all the features of the same in their preferred form will now be given in connection with the accompanying drawings, forming a part of this specification, in which- Figure 1 is a longitudinal vertical section of the water end on one side of a duplex pump which may be of any suitable general construction, such as that of the well-known duplex pump built by Henry R. Worthington. Fig. 2 is a vertical cross-section on the line 2 of Fig. 1. Fig. 3 is a vertical cross-section on the line 3 of Fig. 1. Fig. dis a horizontal section on the line 4 of Figs. 1 and 2.

Referring to said drawings, A A, are the water-cylinders on opposite sides of the pump, and B B the pulsation-chambers for the opposite ends of the cylinders; C and D, the suction and force chambers, which are common to the two sides of the pump; E, the suctionmain, and F the force-main. As shown, the pulsation-chambers are arranged vertically above the opposite ends of the 'pump-cylinders and connected therewith by short passages, and these pulsation-chambers are separated from the suction and force chambers by the composition Valve-plates Gr, which are arranged edgewise to the cylinders and extend transversely thereto and are shown as provided with the common voluntary suctionvalves a and force-valves 1), between which Valve-plates are the suction and force chambers.

In the preferred construction shown the pulsation-chambers for the opposite sides of the pump are cast integral, a single casting having the integral vertical partition 10, forming the two chambers for the opposite sides at each end of the cylinders, and the suction and force chambers common to both sides of the pump are formed by a single casting having the integral horizontal partition 11, dividing the force from the suction chamber.

A single valve-plate G at each end of the cylinders is used, these plates having valveseats, preferably integral therewith, for both the suction and force valves, and these valveplates are secured in place at their edges between the separate castings which form the pulsation-chambers and the suction and force chambers. It will thus be seen that this arrangement of valve-plates ed gewise to the cylinders secures the results-above stated and is very simple and compact, while at the same time it provides for direct and simple connections for both the suction and force mains and for convenient hand-holes, as shown, by which access is had to all the water-valves. When the chambers and valve-plates for opposite sides of the pump are formed integral and arranged as shown, it will be seen that a construction very simple and cheap of man ufacture is provided, but few castings being required and these of simple form.

It will be understood that modifications may be made in the construction shown without departing from the invention, and I am not to be limited to the exact form or arrangement illustrated. Thus while I have shown the valve-plates as extending in planes transverse to the pump-cylinder it will be understood that they may be arranged so as to extend in planes longitudinal of the cylinder in some cases, but that shown is the preferred construction.

While the invention is of especial value in pumps in which the character of the liquid pumped makes it desirable that the valveseats and valve-plates should be of special material, it will be understood that the use of the invention is not thus limited, but that it may be applied also to other classes of pumps.

\Vhile the invention has been illustrated as applied to a double-acting and duplex pump, and certain features of the invention relate to pumps of these classes, it will be understood that it is applicable generally in pump constructions, whether single or duplex. The form of such construct-ions will be clear from the illustration and description of the duplex pump shown herein.
